    Great for the price.

    Work great on my 2018 xp4 Turbo. I mounted them on stock rzr wheels, took a bit of starting fluid to set the bead but after that they have been great.

    STI Chicane

    I'm giving these tires a perfect score based on initial impressions. They seem predictable and are quick to respond in medium to hard packed soil. The only problem I've had was certainly user error, do not run these tires on the road with more than 10 psi. Things get very dicey. I was concerned with the heavy sidewall ruining the ride but once I played with the pressure, they responded like the stockers.
